McDonald’s Corp. said hackers accessed some customer data in South Korea and Taiwan, adding the fast-food chain to the growing list of companies grappling with cyberattacks in recent weeks.

After discovering unauthorized activity on its network, the company determined that “a small number of files were accessed, some of which contained personal data,” according to an emailed statement Friday. The access has been closed off, and no customer payment information was in the breached files, McDonald’s said.
